The RSPile support type in Slide works in conjunction with the Rocscience pile analysis program RSPile.
Pile properties are defined in the RSPile program, which computes the mobilized lateral and/or axial resistance along the length of a pile, for a given soil geometry and loading conditions.
The pile support force used in the Slide analysis is then determined by the location and angle of the slip surface intersection with the pile.
For a detailed example see Tutorial 30 - Analyzing Pile Resistance using RSPile. For information about RSPile click here.
If you have already defined properties and saved an RSPile file, then you can read in this file by selecting the Choose file option.
If you are defining a new RSPile file, then select the Run the RSPile Utility option, to enter the pile and soil properties and save the file.
For more information see the Import RSPile into Slide Summary.
Out of Plane Spacing
The spacing between piles in the out-of-plane direction (i.e. along the slope).
You may choose Axial, Lateral or Axial and Lateral.
The Soil Displacement is the allowable soil displacement along a slip surface at the point of intersection with a pile.
Maximum - this allows you to enter a maximum (limiting) value of soil displacement
Ultimate - in this case the soil displacement is allowed to increase until yielding of the pile
For RSPile support, the default method of Force Application = Active. See the Force Application topic for a discussion of the significance of Active and Passive support force application in Slide.
For RSPile support, the orientation of the applied support force depends on the Resistance type.
If the Resistance Type = Lateral, then the orientation of the support force will be perpendicular to the pile.
If the Resistance Type = Axial, then the orientation of the support force will be parallel to the pile.
If the Resistance Type = Axial and Lateral, then the orientation of the support force will be at some intermediate angle determined by the RSPile analysis.
